RE: All of these ARFs being massed produced...
A guy over on the Profile Brotherhood was into building for profit while he was back in school. Base build price for a kit build to bare bones stage was the price of the kit. Covering in simple two colour was extra and once again $50.00 min. (cost of three rolls mono for 40 size) Turnkey ready for flight was extra again. You covered the cost of kit ,covering, and supplied the servos linkages and motor.
Shipping extra.
The finished ready for flight labour cost for a 40 size easily topped $300.00 plus the materials. Not many were willing to pay that much but those that did were very pleased with the planes.
Brutis was able to make enough @ this to star in school and keep the Wolf away until he finished school and re started work.
He no longer builds for hire.
